i get confused, are they a-14 and a-15 block the same?

and will an a-14 head bolt straight onto an a-15 block and all the water galleries and oil galleries match up?

are the a-14 and a-15 heads essentially the same, size/shape?

The a14 and a15 block are like twins, some small changes but nothing to worry about!! The a14 head will bolt straight on to the a15 block and it matches all the galleries..... a14 and a15 heads are also like twins despite the combustion chamber which is bigger in the a14 head like discussed earlier!!!

cool just wanted to be 100% sure, thanks again, your turning out to be a fountain of fantastic info

I have been in your shoes...... I know how much help it is to get advice from those who have learned from their mistakes.....

Im still on dont worry about that email 1200RC ill give it a go here.
Heads interchange from 1000 to 1500,oil gallaries do vary over the makes ezy fix that one.CC and valve size on the later 1200 to 1500.Them holes for water are on the side of head for manifold, 3 off them under inlet ports.I can change CC but it takes time to do it rite (time i have not got to biszy on 2 B210 for twin girls)

nah thats cool, all understood now, if you want to email or pm or post here a price for the head i reffered to that would be great thanks mate
